How to Choose the Right Buried Composite Pipe for Your Gas Station
Selecting the correct underground composite pipe system for your gas station is a critical decision that affects safety, compliance, and long-term operational costs. Here is what you need to consider.
Key Selection Factors
1. Pipe Diameter and Wall Thickness
Standard diameters for gas station underground pipes range from 50mm to 100mm. The correct size depends on your station fuel flow requirements. WoHong Petrochemical offers a full range of sizes to match any station layout.
2. Double-Wall vs Single-Wall
Modern regulations increasingly require double-wall composite pipes with built-in leak detection channels. The space between the inner and outer walls allows continuous monitoring for any fuel leakage, providing immediate alerts.
3. Fuel Compatibility
Quality buried composite pipes must be compatible with gasoline, diesel, ethanol-blended fuels, and methanol. WoHong Petrochemical pipes are tested and certified for all common fuel types.
4. Temperature and Pressure Ratings
Verify that the pipe system can handle the operating temperatures in your region. Composite pipes from WoHong Petrochemical are rated for -40°C to 80°C and working pressures up to 1.6MPa.
Installation Considerations
Proper installation is as important as pipe quality. Key points:
- Trench depth: Typically 600-1200mm depending on frost line and load requirements
- Electrofusion welding: Ensures leak-proof joints
- Pressure testing: Must be performed before backfilling
- Leak detection system: Must be connected and verified
